TITLE: Deconstructing synthetic biology across scales: A conceptual approach for training synthetic biologists —ABSTRACT: Synthetic biology allows us to reuse, repurpose, and reconfigure biological systems to address society’s most pressing challenges. Developing biotechnologies in this way requires integrating concepts across

TITLE: Disproportionate carbon dioxide efflux in bacterial metabolic pathways for different organic substrates leads to variable contribution to carbon use efficiency —ABSTRACT: Microbial organic matter turnover is an important contributor to terrestrial carbon dioxide (CO2) budget. Partitioning of organic carbons

TITLE: Phosphorus recycling by mineral‑catalyzed ribonucleotide cleavage on iron and manganese oxides —ABSTRACT: Phosphorus is an essential element influencing both food security via plant fertilization, and water pollution through excessive phosphorus use, yet the phosphorus cycle in ecosystems is poorly

TITLE: Electrostatic coupling and water bridging in adsorption hierarchy of biomolecules at water–clay interface —ABSTRACT: Clay minerals are implicated in the retention of biomolecules within soil organic matter in many soil environments. Spectroscopic studies have proposed several mechanisms for biomolecule

TITLE: Microbially induced precipitation of silica by anaerobic methane-oxidizing consortia and implications for microbial fossil preservation —ABSTRACT: Authigenic carbonate minerals can preserve biosignatures of microbial anaerobic oxidation of methane (AOM) in the rock record. It is not currently known whether

TITLE: An integrated systems-biology approach reveals differences in formate metabolism in the genus Methanothermobacter —ABSTRACT: Methanogenesis allows methanogenic archaea to generate cellular energy for their growth while producing methane. Thermophilic hydrogenotrophic species of the genus Methanothermobacter have been recognized as

TITLE: Physiological and evolutionary contexts of a new symbiotic species from the nitrogen-recycling gut community of turtle ants —ABSTRACT: While genome sequencing has expanded our knowledge of symbiosis, role assignment within multi-species microbiomes remains challenging due to genomic redundancy and

TITLE: Complex regulation in a Comamonas platform for diverse aromatic carbon metabolism –ABSTRACT: Critical to a sustainable energy future are microbial platforms that can process aromatic carbons from the largely untapped reservoir of lignin and plastic feedstocks. Comamonas species present

TITLE: Selectivity in Enzymatic Phosphorus Recycling from Biopolymers: Isotope Effect, Reactivity Kinetics, and Molecular Docking with Fungal and Plant Phosphatases –ABSTRACT Among ubiquitous phosphorus (P) reserves in environmental matrices are ribonucleic acid (RNA) and polyphosphate (polyP), which are, respectively, organic

TITLE: Metabolomics analysis of unresolved molecular variability in stoichiometry dynamics of a stream dissolved organic matter –ABSTRACT: Broad molecular classification based on stoichiometric ratio relationships has been used extensively to characterize the chemical diversity of aquatic dissolved organic matter (DOM).
